Quick notes:
- purple's green crab camp has only one murloc
- ogre camp on the left aggroes the golem camp behind it

I'm not really that knowledgable about 2v2, so I'll leave it to others. I appreciate the boats here, as always. Terraining/doodads could imo be more profound, some doodads could give it an identity so that it won't be just another "brown map". Eg. you've mentioned a forest shrine in the map description, why not create some neat stufff with doodads.
Maybe the tavern is a bit too close to the bottom players, it could give an upper hand to the attacker (I see the tavern's position was determined by the diagonals between the bases and expos of each team but still...).
The marketplace is going to have some fat loot at the end of the day with those L6, 2xL5 and L4 items.

@Knecht this map has some work for sure. For me the biggest problem is the walking distances to the enemy main bases. I'd like to have it shorter here. In terms of boat play I like the upper water route but other than that the map doesn't offer anything special. Lv 6 perma and market combo could be quite fun and in the end fun map this is. The perfect circle islands and the whole raccon face thing makes map look unnatural. Id like to rework the whole tileset and make it look more like in ruins of azhara. Raccoon shrine would be amazing I wanna make that for sure

Well, except for the boats, it's a solid but unspectacular map. I like the selection of creeps though. Itemdrops also look. Other notes:
1. For the sake of symmetry, the missing creep mentioned by @Knecht should be added.
2. The murlocs at the northern green camps ensnare scouts. They should even get aggroed by scouts.
3. Visually, I think the map would benefit a lot if some areas would look clearly different from others. This also helps to recognize a structure in the map and makes it easier to judge distances.
4. Many of the stronger camps have very limited antiair capabilities.
5. Did you intentionally not use the forest trolls berserker/highpriests, as they would be too "green" to fit into the map?
6. On closer look, I like that for 2v2 both players in each team have slightly different starting positions/expansion layout.

So, the only real bug is the missing the creep. Not enough to not approve a map of this size. Still, there's lots of room to improve it, if you feel like it. But if you ultimately dream of getting a map to ladder, this one wont be it. Anyway, map approved.
